Please help

Well there is 3 things that/a car needs to run. 1 gas 2 air 3 spark Check any of those first

We have checked all those. It will start if we push start it and continue to start after that. It seems to not want to start when cold.

Sounds like the iac is bad... that is intake air control That is what make the car idle high when cold and drops rpm when engine gets hot

Ok so we have replaced A lot of sensors and still nothing. It will crank over but won't start. Have to push start. But after its warm it will start ever time.

We have replaced the cam sensor the crank sensor and another sensor. Still can't figure it out.

Have you checked for any vaccume leaks? Bad hoses can cause it to have rough idle. Also one last thing, it could be the ecu. From readimg forums the capacitor (s) they are large in diameter black and when you look down on them it has a silver circle, they can blow out and will discolor. Normal is silver top bad is yellow. And smells fishy. Other than that if every sensor has been replaced providing they are good. Sometimes you can by a bad one but if all is well then it goes back to the ECU. That controls and monitors all sensors giving it a proper reading to run and maintain engine performance. Bent valve? Compression loss can make it not start or run I believe these cars are interference motors so if the timing belt broke could cause the valves to be bent from pistons Do a compression check On last check out is bad grounds. Clean up any grounds that are not in good contact to the metal!
